Technically we don't know what the theatrical animated movies are going to do. The first one is going to be focused on the main Avatar characters again and be directly canon to the original show, so it's possible that they might take something from the comics. (But it's also still possible that they might do something else entirely; an adaptation of anything from the comics would have to pretty much assume the audience had seen the show, which Paramount might not want to do for a theatrical movie.)
